Original application filed April 5, 1924, Serial No. 704,393. Divided and this application filed November To all whom it may concern:

Be it known that I, CHARLES DAVID BON- SALL, a citizen of the United States, and a resident of the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a certain new and use ful Improvement in Carlines, of which the followingis a specification.

The subject-matter hereof is divided out of my pending application Serial Number 704,393, filed April 5, 1924, for patent for flexible car roof.

The present invention relates to carlines, particularly adapted to be assembled into. a car roof construction embodying the invention set forth in my said pending application. The principal object of the present invention is to devise a carline that will-not only serve to carry aconsiderable vertical roof load and ofl'er considerable resistance to stresses: that tend to distort the car frame, but will also serve to weather proof the joints between the roof sheets and support the sheets so that they are enabled to accommodate themselves to the distortions of the framework. Another object i to pro duce a carline of great strength and light weight andof simple and economical construction. The invention consists principally in the improved carline hereinafter shown and described; and it also consists in the arrangements and combinationsv of parts hereinafter described and claimed.

In the accompanying drawing, which forms part of this specification and wherein like numeral refer to like parts wherever they occur Fig. 1 is a plan view of a portion of a car roof provided with carlines embodying my invention, 7 a a Fig. 2 is a section view on the line 2 -2 of Fig. 1' crosswise of the car,

Fig. 3 is a cross sectional View on the line 3--3 of Fig. 1 through a carline and adjacent portions of the roof sheets, and

Fig. 4 is a detail view of a shoulder bolt. In the present construction, there are carlines A that are supported by the side plates main member.

19, 1924. Serial No. 750,841.

The carline comprises a main member 3 made of heavy sheet metal, which i preferably galvanized. .This main member is of inverted channel shape and has horizontal I side flanges l at the bottom thereof, inside of this main carline member is an auxiliary member 5 of the same cross section but of considerably less width and depth than said For the sake of economy, thi auxiliary member. is preferably made of a sheet of black iron, and it is secured flatwise against the undersurface of said main member by suitable rivets 6 (with washers 7 interposed,.ifdesired), whereby said members are enabled to cooperatein taking care ofthe stresses to which the carline is. subjected in practice. v

Formed integrally with the rivets 6 on the underside thereof are a spacer or distance piece 8 andbolt portion 90f reduced diameter which is threaded to receive a nutlO.

The rivet, spacer and threaded portion are hereinafter referred to collectively as a rivet .bolt or shoulder bolt. Any suitable locknut 11 may be used to keep the nut tight. Interposed between the several nuts 10 and the lower offsets or shoulders of the respective shoulder bolts is a supporting strip or strips 12 of inverted channel section. The length of the spacer 8, that is, the distance fromthe upper shoulder of said shoulder bolt (being the shoulder that bears against the under surfaceof the auxiliary member of the carline), to the lowershoulder of said shoulder bolt (being the shoulder against the under side of which the supporting strip bears), is such that a space 13 approximately equal to the thickness of a roof sheet intervenes between the horizontal flanges of said auxiliary carline member and said sheet supporting strip 13.

The ends 14 of the main carline member are bent;downwardly without great change of section and are secured to the sub-structure by horizontal bolts 15 that extend through the said flanges of said main carline member, the side plate 1 of the car andany other portions of the structure that may intervene between them. In the particular construction illustrated, said bolts 15 are shown passing through the side sheathing 16 of the car, which terminates short of the top of the side plate, and also through the downturned portion of an angular metal fitting 17, (whose horizontal portion rests on the top of the side plate and is secured by a vertical bolt 18 passing therethrough) and also through the vertical portion of an angular flashing strip 20 that is bent inwardly over the side plate.

. The roof sheets are of heavy gage metal and extend lengthwise from side plate to side plate, being preferably corrugated lengthwise. The ends of these roof sheets have downturned flanges 21 which lie in the spaces 22 above the side sheathing that intervenes between the side plates and the downturned ends of the carline, where there is sufficient clearance to permit the sheets to accommodate themselves to distortions of the car frame. The side margins 23' of the sheets are offset upwardly, that is, they are bent upwardly and thence horizontally outwardly. The horizontal portions lie in the spaces 13 above-mentionel betweenthe auxiliary carline member and the sheet supporting member; and the vertical portions lie between the side flanges of the supporting member and the vertical sides of the main carline member, where ample clearance spaces 24 are provided to permit the sheet to adapt itself to the distortions of the car frame. A I

By the foregoing arrangements of parts, the sheets are supported along their sides by the supporting plates secured to the carlines, but otherwise the sheets are free to move to such limited extent as may be necessary to accommodate themselves to any distortions of the car frame that are likely to occur in service. It is noted that there are no perforations in the sheets and that the downturned flanges at the ends of the sheets are counted on to prevent the sheets from slippingcrosswise of the car to an excessive extent.

One of the principal advantages of the foregoing construction is the facility with which it may be applied. In applying this roof, the? sheets are first placed in position, the oarlineg (without the supporting strips) are then located over the sheets and in proper relation thereto, and then the supporting strips are secured to the carlines. As the carlines are positioned with reference to the sheets and the clearances required at the sides thereof, inaccuracies or variations in the widths of the roof sheets do not entail the consequences that would be so serious if the carlines were all fixed in place first.

What I claim is:

1. A carline comprising a main member of inverted channel section having horizontal flanges, an auxiliary member of substantially the same cross section extending longitudinally of the carline and rigidly secured flatwise against the under surface of the web of the main member, the ends of the main member being bent substantially vertioally beyond the ends of the auxiliary member.

2. A carline comprising a main member of inverted channel section having horizontal flanges, an auxiliary member of substantially the same cross section extending substantially from end to end of the carline and permanently secured flatwise against the under surface of the web of the main member, the ends of the main member be ing bent substantially vertically beyond the ends of the auxiliary member. A s

8. A carline comprising a main galvanized iron member of inverted channel section having horizontal flanges, an auxiliary member of black iron extending longitudinallyof the main member inside thereof and of substantially the same cross section rigid- 1y secured fiatwise against the under surface of the web of the ,main'member, the hori- I zontal flanges of the auxiliary member being higher than the horizontal flanges of the main member.

4. A carline comprisinga main'member of inverted channel section having horizontal flanges, an auxiliary member inside thereof and of substantially the same cross section rigidly secured flatwise against the under surface of the web of the main member, the

horizontal flanges of the auxiliary member being higher than the horizontal flanges of the main member, and a sheet supporting strip secured inside of said carline below the horizontal flanges of said auxiliary member.

,5. A carline comprising a main member of inverted channel section having horizontal flanges, an auxiliary member of substantially the same cross section rigidly secured flatwise against the under surface of the web 'of the main member by rivets that have threaded shoulder bolts integral therewith and extending downwardly therefrom beyond the ends of the auxiliary member, and

a sheet supporting strip secured inside of said carline by said shoulder bolts.

6. A carline comprisinga main member of inverted channel section having horizontal flanges, an auxiliary member of substantially the same cross section rigidly secured flatwise against the under surface of the web of the main member by rivets that have threaded shoulder bolts integral therewith and extending downwardly therefrom, and stantially the same cross-section rigidly sea a sheet supporting strip secured inside of cured flatwise, against the under surface of said carline below aid auxiliary member by the web of the main member, and a sheet 10 said shoulder bolts. su porting strip secured to said oar-line.
